Anaphylaxis predictors assessment
Children were grouped according to reaction severity for anaphylaxis risk assessment. Patients with a reaction compatible with anaphylaxis (definition based on Muraro et al. criteria12,14) were included in group 1 (G1), while those with a milder reaction (oral allergy syndrome or systemic reaction without severity to fulfil anaphylaxis criteria) were included in group 2 (G2). The following variables were compared between groups: MPD of ST (for methodologic uniformization only SPPT were considered in this analysis), sIgE and mcIgE values, as well as ratio sIgE/total IgE.
